Tire Experts?

I just switched from Carlisle ST 225/75R15C with a 50 PSI max to Maxxis ST 225/75R15D 65 PSI max. What PSI would you run these load D tires at. MY GVWR is 9015lbs.
  • 65 psi regardless of what the rim says - 15 psi is nothing to the wheel.
  • What are your rims rated for? I've never seen a rim come apart due to excess PSI but 65lb. in a 50lb. rim is a 30% overload. Do you have a TPMS? If not, that would be my next purchase.
  • I'm an expert on nothing...but here is the load chart for your tires.
    I'd run them close to max. That's what I do with our Maxxis. (I'm running LR E's) This will give you some margin.

    Hope this helps......Maxxis Load Chart HERE
  • 60-65 depending on how they wear..

    I went to LR D tires on my little #5000 TT and I run them at 60 and so far so good.. :)
